Give a function C that can represent the cost of buying x meals, if one meal cost Php 30.
C = 30x
The function C that represents the cost of buying x meals can be defined as:
C(x) = 30x
In this function, 'x' represents the number of meals being purchased, and 'C(x)' represents the cost of buying those meals. Since each meal costs Php 30, multiplying the number of meals by 30 gives us the total cost.
To represent the cost of buying x meals, if one meal costs Php 30, you can use the equation:
C(x) = 30x
In this equation, C(x) represents the total cost and x represents the number of meals purchased. By multiplying the cost of one meal (30) by the quantity of meals (x), you can calculate the total cost of x meals.
